A transmission channel is a fundamental element in a communication system, which provides the means to transmit information from a transmitter to a receiver.  In reality, these channels vary with time, which leads to a unstable performance of a communication system. The goal is to test or evaluate new models, algorithms and applications which involve acoustic channels.

Within the scope of this talk, a method to simulate time-variant acoustic channels in real-time is proposed, in which time-variant acoustic channels have been generated in different environments scenarios and with a specific number of moving reflectors. Furthermore, with the efficient convolution and complex impulse response generation method, the computation complexity has been improved in comparison to the formal usages.
